What sort of improvements can I expect?

The tune is designed to give a conservative yet exhilarating 10% improvement in performance. With this Hondata performance upgrade, your Accord will match the performance of many more expensive luxury cars.

Your Accord gains anywhere from 10 to 40 hp everywhere, with the maximum gains not at the top of the rev range, but where you need it most at the low end of the rev range. Rapid acceleration is just a quick flex of the throttle pedal away. 91 or higher octane recommended.

Accord MT 2.0 Flex Fuel

Flex fuel kits are now available for the Accord from retailers like ProCivic. In combination with FlashPro Manager 3.4.0.0 or later the Accord becomes a fully flex fuel compatible vehicle. These tunes were developed on a completely stock MT and AT Accord. The Accord Flex-Fuel calibration will automatically adjust the tuning and boost levels to maximize the performance based on your ethanol content.

Explanation of MT dyno chart

Over E50 the boost is reduced based on the ethanol content to stay within the limits of the fuel pump

Accord AT 2.0 Flex Fuel

Flex fuel kits are now available for the Accord from retailers like ProCivic. In combination with FlashPro Manager 3.4.0.0 or later the Accord becomes a fully flex fuel compatible vehicle. These tunes were developed on a completely stock MT and AT Accord. The Accord Flex-Fuel calibration will automatically adjust the tuning and boost levels to maximize the performance based on your ethanol content.

Explanation of AT dyno chart

The dyno chart is a little wavy because of the interaction of the AT and dyno. The MT dyno plot above gives a more accurate representation.

Stock - as stated

FlashPro - E10 pump gas and Stage 1 tune

E40 and FlashPro - E40, FlashPro and more boost

We've put together a series of training videos to describe the function and use of the FlashPro. View the videos in High Definition Full Screen to view the screen shots.

FlashPro Introduction

Hondata's new generation programming tool for the 06 - 09 US Civic Si, the Japanese 06-09 Civic Type R and the European 07-09 Civic Type R. A brief introduction.

FlashPro getting started

This video covers the installation the FlashPro Manager software, the USB drivers, software registration and upload of a calibration.

Live Tuning

One of the latest features added to FlashPro, live tuning gives you the ability to tune your Honda or Acura on the fly without switching off the engine. Live tuning simplifies part throttle tuning and significantly reduces the time and cost of tuning your car.

Race Calibration

Hondata has developed a Race calibration which allows you to tune with the MAP sensor and bypass the limitations of the AFM sensor. A look at the tuning principles for forced induction on a modern return-less fuel system.

Datalogging and Air fuel ratios

A look a the extensive datalogging capabilities of the FlashPro and the many ways in which to examine your engine data. We touch on the datalogging of the air fuel ratios and how you can use it to adjust your tuning.

The FlashPro uses software called FlashProManager for tuning & datalogging.

All FlashPros since sold since 2014 support Bluetooth

Civic Turbo owner feedback

Yup definitely one of the best mods you can get right now. Forget the intake, exhaust, bov or whatever rice stuff. This is the best bang for your buck for power.

FlashPro at 20-21psi i can get 5.7-6 seconds 0-60

Still getting 30-47mpg on the highway depending how many hills I got to climb

Syntec:

What won me over initially was throttle response and how much more torque the car had. The moment when my foot went to the floor on the gas, the first thought was, "Oh shit!" and honestly was surprised it was the same car I have except properly tuned. (Hellooooo wheel-slip ).

Silverghost

Oh yea it hauls some ass for sure.

SilverDyme

It's like night and day.

Let me tell one thing...it pulls HARD on the street wow!

dallasjhawk

The car sits you back in your seat and the traction control kicks in under full throttle bc the tires will break loose as max boost hits. Maybe its the cool weather helping it lose traction but it doesnt do that on the stock tune. And it feels effortless for this car to pass at freeway speeds when giving it some gas pedal.

sarknatron

The quickest 0-60 time I've been able to pull using the torque app was a 6.3... I feel a huge difference between stock and using the flashpro.. It pushes you back in your seat
